more than diameter apart, and plaiiily farther from the eyes; lateral bosses 

 small, situate much lower than the ocelli, and twice as far from ocelli as from 

 eyes. Pronotum one and one half times broader than long, slightly naiTowed 

 behind; setae about as long as the abdomen. Wings moderately long, one 

 branch to radial sector, which is much nearer to anastomosis than to the tip; 

 anastomosis disjointed, the upper part nearly straight across, tlu'ee median 

 and cubital cross- veins, all far apart; subcosta runs out to the anastomosis, 

 one weak cross-vein beyond it. 



Length of body 6 mm., of fore wing 8 mm. 



Neoperla viscayana, sp. nov. 



Type. — M. C. Z. 10,827. Philippines — Luzon: Nueva Vizcaya; 

 Imugin (C. F. Baker). 



Dull sordid yellowish, a black mark including the ocelli, blackish in front on 

 middle of head; palpi brown; antennae black except the basal joint pale; 

 pronotum scarcely embrowned each side; all tibiae brownish, femora yellow, 

 tarsi dark on tips. \Mngs almost hyaline, veins dull brownish yellow. Ocelli 

 large, about one and one fourth diameter apart, more than two diameters 

 from eyes; lateral bosses about size of ocelli, transversely elliptic, as near to 

 ocelli as to the eyes; pronotum one and one half times broader than long, 

 narrowed behind. Wings with radial sector two- or three-branched beyond the 

 anastomosis, latter scarcely disjointed, the upper part straight across, two or 

 three cross-veins beyond end of subcosta, six to eight median and cubital 

 cross-veins. Ventral plate of female slightly convex on hind edge. 



Length of body 10 mm.; of fore wing 13 mm. 



x\ male, probably of the same species, from the island of Penang, 

 is eight millimeters long; the tibiae are scarcely darkened, the pro- 

 notum rather longer, and lateral bosses larger. 



Neoperla remota, sp. nov. 



Type.— M. C. Z. 10,835. Brazil: New Freiburg (Bescke coll.). 



Related to A'', dilaticollis, but ocelli more remote. Reddish brown; head 

 more or less blackish in front, pronotum darker on sides, but not with a definite 

 stripe; mesonotum with two dark spots; abdomen pale, the segments below 

 marked with black; antennae and palpi brown. Wrings tinted as in A'', dilati- 

 collis, veins dark, costa not paler; four costals beyond end of subcosta, ten 

 before; about nine median cross-veins and five cubital ones; radial sector 

 forks twice beyond anastomosis; .anastomosis not disjointed, upper part not 

 oblique; legs pale, rather golden, front femur and tibia plainly dark before tip,
